My invention relates to improvements in mixing devices.

()ne of the objects of my invention is to provide a novel mixi .g deviceadapted for inser- 3 tion between a carlnireter and a manifold, wherebywute", preirrably in vapor form, and air may be intimately mixed withthe fuel mixture drawn from the carbureter into the manifold.

A further object of my invention is to provide a mixing device of thekind described, which is simple, cheap, durable, which is not liable tobe clogged, which will ei'ect a thorough iateriningiing of the fuel nare with 1:) water vapor or water vapor and air, or of air alone, whichis durable and not liable to get out of order, and which can be easilyand readily applied by an unskilled person to explosivc engines now inuse.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing, which illustrates the preferred embodimentof my invention,

Eng. 1 is a side elevation of my nnproved mixing device shown mounted inoperative position between a carbureter and manifold of usual. type.

Fig. 2 is an enlarged central vertical sectional view of the same.

Fig. 3 is an enlarged perspective view of the mixing device with thefans, washers, and pins removed.

Fig. 4 is an enlarged view partly in longitudiual section and partly inelevation of my improved mixing device.

Similar characters of reference designate similar parts in the differentviews.

My improved mixing device is provided with a plate 1, which is adaptedto be inserted, as shown in Figs. 1 and 2 between a carbureter C and amanifold M, the ends of the plate having respectively t vo notches 2adapted to receive the securing bolts, one of which, designated by B, isshown in Fig. 1, which fasten the carburetor to the mainfold. tlaskets 3may be inserted between the plate 1 and the manifold and carbureter.

The plate 1 is provided with a bridge por tion 4, which extendstransversely across a passage 5 through the plate 1, said passageserving to connect the passages of the carburetor and the manifold.

The bridge portion 4 is centrally disposed and at opposite edges isrespectively provided DEVICE.

with two horizontal bearings, which may be oppositely extending centraltrunnions 6, which may be integral with the bridge portion l', and uponwhich are respectively rotatablv mounted twt fans 7 and 8, which are,provided with oppositely disi l i 7 pose-d blades 5% and it), by meansof which a cm rent 1 thud passing through the passage 5 wil I the fansin opposite directions.

d the fans on trunnicns (3 respectively are mounted iers l2.

The plate l is provided with a lateral threaded hole l3 c nnmunicatingwith the pask 5 at one side of and adapted to discharge \iatcr vapor oair or both simultaneously against one side of the bridge portion 4,which is disposed transversely to said hole. The hole 13) provides aninlet for the water vapor so arranged that the bridge portion 4 willserve to deflect and diffuse the fluid discharged from the inlet intothe passage 5.

As the water vapor and air is diffused by striking the bridge portion 4it will be thoroughly intermingled with the current of fuel mixturewhich is passing through the passage 5. The fan 7 revolving in onedirection will tend to intermingle and revolve the fuel mixture and thewater vapor and air in one direetirm, and the fan 8 will, by revolvingin the opposite direction, etlect a still better admixture of the. vaporair and fuel mixture.

As shown, the blades 9 and 1t) of the fans, may each have perforations,ll, to reduce the l'tHl ltttllt't, oil'cred by the blades to the suetionctt'ect of the engine, and to assist in the inter-mingling of the vapor,air and fuel mix ture.

In the operation of the mixer, when the engine effects a suction throughthe passage from the carburetor C, the fans 7 and 8 will be revolved inopposite directions thus intermingling the water vapor and air enteringthe passage. 5 through the inlethole 13, the vapor and air on strikingthe bridge portion will be deflected and diffused between the fans,thereby making more perfect the thorough intcrmingling of the vapor andair with the fuel mixture. The bridge portion 4, thus located. effectsthe double function of a deflector and mixer and of a support for thefans.
